Ellenblum et al. (2015:5) estimate that ~2.5 m of displacement is attributable to a single event which, though dated broadly between the 3rd century BCE and ~142 BCE, most likely struck around 142 BCE. Ellenblum et al. (2015:3) describe two Hellenistic building phases, an early and a late phase, with the later constructed atop the former. Although the Northern Hellenistic Complex was too disturbed to trace walls across the fault, the southern compound in Area E allowed structural reconstruction. Two phases are separated by a destruction event. The earlier walls are straight over ~20 m except within the fault zone, where they are bent left-laterally. Collapse debris included vessels, cooking pots, fishplates, relief bowls, imported wares, and a hoard of 45 bronze coins. Of 32 datable coins, most cluster in the 150s–140s BCE, with the latest minted in 143/142 BCE. Ellenblum et al. (2015:4) interpret the coin hoard as consistent with sudden wall collapse, possibly earthquake-triggered. The 143/142 BCE coin provides a terminus post quem for the earthquake that ended the early phase, after which the late Hellenistic walls were built. A comparable abrupt termination at Tell Anafa may reflect the same regional event. Reconstruction of the early wall to a straight alignment requires ~6 m of total displacement. This 6 m represents slip from the Late Hellenistic earthquake and all subsequent events. Of this, ~2.5 m is attributed specifically to the Late Hellenistic rupture.
